METHOD OF SETTING EYELETS.

Application filed June 15, 1918.

To all whom it may concern:

Be it known that I, SYLvEs'rER L. GOOKIN, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain Improvements in Methods of Setting Eyelets, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to a method of setting eyelets in telescoping relation and particularly to a method in which the setting of the two eyelets is performed as a single operation.

. In order to secure greater'holding power -where eyelets are set in heavy work such as army shoes or leggings, the eyelets heretofore have been provided with a reinforcing washer or else, in some cases, two eye-. lets have been set in each hole, first one from one side of the work and then a smaller one inside the first and from the other side of the work so that their flanges are oppositely disposed. Complicated and expensive machinery is required if the reinforcing washer is to be used, unless the eyelets and washers are set one at a'time by hand, and, if two eyelets are set successively in each hole, the operating time is doubled.

An object of the present invention is to devise an improved method of setting eyelets in telescoping relation, according to which the two eyelets may be simultaneously inserted from opposite sides of a piece of work and secured therein by a single operation.

In one of its aspects the invention consists in substantially simultaneously inserting from opposite sides of the work eyelets having barrels of different sizes, so that the barrels will be guided one through the other, and in upsetting the barrel of the larger eyelet by engagement with the inner face of the flange of the smaller eyelet. Preferably, the barrel of the smaller eyelet will be clenched in holding engagement with the flanged end of the larger eyelet.

In another aspect, the invention consists in supporting and inserting the larger eyelet by means of a tool having a tapered projecting member or pilot which tapers away from the barrel of the larger eyelet, and in guiding the smaller eyelet into telescoping Specification of Letters Patent.

relation with the larger eyelet by passing it along and in close engagement with the tapered member.

From another viewpoint, the invention consists in presenting eyelets to opposite sldes of a piece of work, guidin them into telescoping relation, and in braclng the barrel of the smaller eyelet internally and externally to prevent buckling.

The preferred means for practising the invention will be most readily understood from a consideration of the following specification taken in connection with the accompanying drawings, in which,-

Figure 1 is a sectional view through the punching tools, and

Figs. 2 to 5 are sectional views through the setting tools showing them in various and successive positions as the eyelets are presented to and set in the work.

In carrying out the novel method which constitutes the subject-matter of this invention, it will be understood that various types of punching and setting tools may be utilized and that those shown and described herein are only essential to the proper carrying out of the method in so far as they are required by the terms of the claims. An aperture will beformed in a piece of work 10 comprising one or more layers of material by cooperating punching tools such as a. punch block 14 and a tubular punch 12 which, it will be seen, is provided with a tapered exterior surface so that the hole formed in the work is larger at one end than at the other.

Eyelets are then inserted into the hole in opposite directions and in order to secure the best results it is desirable to have a short tapering portion at the leading end of the barrel of the smaller eyelet so that the latter may be supported more conveniently by frictional engagement with its internal surface, and so that entrance of the smaller barrel into the larger barrel will be facilitated. Further, the larger eyelet may advantageously be formed to provide an annular space adjacent to the point where its barrel joins its flange, in which space the upset portion of the smaller eyelet may be curled to interlock the eyelets when the two are set in telescoping relation. It will be assumed that the larger eyelet is to be presented from the under side of the work because this has been found the more advantageous arrangement for the reason that it enables the larger eyelet to be easily su orted" and guide into the hole in the wor his larger eyelet may desirably be presented to the Work by means of a settingmay conveniently be provided with an annular groove 36 shaped to fit the flange of the larger eyelet 38. The annular ridge or shoulder formed by the junction of the surfaces 34 and 36 serves to center the larger eyelet byengagement with the internal surface of the barrel, so that when the leading end of the smaller eyelet is about to enter the barrel of the larger eyelet both eyelets are centered by coaction of their internal surfaces with concentric portions of the set.

ting member 30. The smaller eyelet may conveniently be presented from above to the opposite face of the work by means of a settm tool 20 having a centrally disposed depressi le spindle 22 whose outer end is slightly tapered and is provided with a conical recess 24 for engagement with the upper end of the tapered pilot of the other setting tool. The upper setting tool pref-' erably will be provided with an annular groove 26 shaped to fit the flange of the smaller eyelet '28. Having su plied a smaller eyelet to the upper tool, w 1ch sup- .ports the eyelet by frictional engagement, and having placed a larger eyelet over the tapered pilot 32 of the lower tool, the two tools may be caused to approach the work from opposite sides so that the end of the tapered pilot will pass through a hole in the work 10 and engage the conical recess.24 in the spindle of the upper set at approximately the level of the work and then, as the approach of the tools continues, repel this spindle 22 into the upperset. As soon as the repulsion of the spindle of then per setting tool 20 has brought the flange o the smaller eyelet 28 into engagement with said tool, the smaller eyelet will be disengaged from said spindle and pushed on to the end of the tapered pilot 32. The end of the pilot 32 at this time, as shown in Fig. 3, will have passed completely through the work and will preferably be so dimensioned that the contracted end of the barrel of the upper eyelet will closely engage the same near its extreme end. Preferably the a proaching movements of the two tools Wlll be at substantially the same rate of speed and as the barrels of the two eyelets are brought into the aperture in the work the barrels of the smaller eyelet will be centered by the pilot of the lower tool throughout rejecting member or pilot 32 and its entire course of movement and will be braced thereby against crumgling and contracting, so that'a smooth an uniform passageway for a lacin will be insured. If

at first the larger eye et is not seated on the annular surface 36 it will be held b the pilot portion 32 as shown by Fig. 3, ut it will be lodged on the seat 36 in consequence of initial contact either with the work 10 or with the smaller eyelet. It is thus assured that the larger eyelet will be centered incoaxial relation with the smaller eyelet by the annular ridge or shoulder between surfaces 34 and 36 before the leading end of the smaller eyelet begins to enter the barrel of the larger eyelet. It will be noted that end-to-end abutting of the barrels of the two eyelets is prevented partly by the close engagement between the barrel of the smaller e elet and the tapered pilot of the lower too partly by the tapering formation at the leading end of the smaller eyelet, and partly because the barrel of the larger-eyelet will, even if the tools are su ported in the inclined positionf illustrated as will commonly be the case in some commercial machines, stand away from the tapered pilot all around the latter because of the fact that said tapered pilot tapers awa from the barrel of the larger eyelet. A ter the. two eyelets have been brought into telescoping relation, as shown in Fig. 4, the barrel of the larger eyelet will be guided upon the and will support the barrel of the smaller eyelet against outward buckling in case of variations in the thickness of the work or improper operation of the setting tools. The continued approach of the setting tools will then bring the barrel of the smaller eyelet into engagement with the upsettin surface 34 and cause the same to be clenche .in holdi-n engagement with the internal surface 0 the barrel of the larger eyelet. By reason of the preferred disposition of the upsetting surface 34 above the supportmg surface for the flange of the larger eyelet, the upset end of the smaller eyelet will be curled'and beadedin the final product within the base end of the barrel of the larger eyelet and will not project to the plane'of the crown or embossed portion of the flange of the larger eyelet. At the same time, if the length of the barrel of the larger eyelet is properly proportioned to the thickness of the work in which the eyelets are being set, this barrel-will be brought into engagement with the inner face of the flan e of the smaller eyelet and, as the lat-v outside of the barrel of the smaller eyelet all its refinement, it will be understood that many of the desirable features mentioned are not essential to the carrying out of the novel method which forms the subject-matter of the invention.
